TIRE-PRGTECTING CASNG.

Application filed .Tune 16,

To all whom t 'may concern.'

Be it known that I, PEARL E. STRoUn, a citizen of the United States, residing at South Heart, in the county of Stark and State of North Dakota, have invented certain new and useful Improvements in Tire- Protecting Casings, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in tire protecting casings, and more particularly for automobile tires and is to be used as a protecting armor to the regular tire of an automobile.

The object of this invention is to provide an automobile tire protecting casing that protects the tire and is easily and readily attached to and detached from a tire.

Another object of this invention is to so construct the protecting casing that it not only protects the tire, but will also prevent skidding.

A further object of this invention is to construct a tire protecting `casing having a non-skid element which may be readily renewed.

This invention is adapted to be used with either new or old tires.

In the accompanying drawing- Figure l is a fragmental perspective view of my protecting casing applied to av tire.

Fig. 2 is a cross-sectional view of a tire with my improved protecting casing applied thereto.

Fig. 3 isa top plan view of the protecting casing. i

Fig. t is a detail perspective view of one of the tread studs.

Fig. 5 is a detail perspective view of the bolt used to fasten the two parts of the casing together, the parts being shown in separated relation.

Referring now to the drawings yin detail, in which like references designate similar parts throughout the several figures.

In the drawings, 1 designates the rim of a wheel, on which is mounted in any suitable manner the tire 2.

The mounting of the tire on the rimorms no part of this invention and in the drawings is shown what is known as the clencher tire and rim.

My improved protecting casing comprises a piece 3 curved in cross-section, which iits one side, the tread and about a quarter of Specication of Letters Patent.

the other side oi the tire throughout its periphery. The remainder of the tire is carried by the curved strip 4i, which overlaps slightly and is fastened to the piece 3 by bolts spaced intervals throughout the periphery t the casing.

TheseA bolts comprise a square shank 5', with a rounded head 6, which rests against the outside of the tire 2. The shank 5 is provided with a screw threaded opening 7. The two parts of the protecting casing 3 and 4E are provided with squared openings 8 and 9 through which the shank 5 extends outwardly.

When the openings in the members 3 and e are matched and the shank 5 has been thrust outwardly through them, the fastening is completed by inserting the screw 10.

into the opening? ot the shank 5 until the two parts of the casing are tightly clamped together.

Upon the member 3 of the casing is fastened a tread ll by suitable countersunk rivets l2, with heads 13k. The tread is provided with screw-threaded openings 14, into which screwed the studs or calks l5, which may have a head of any desired shape but preferably rounded, as shown in the drawings.

This protecting casing is made preferably of steel, as is also the tread ll, but it is understood that this easing could be made of some other materialv without a departure from the spirit of this invention.

it will be `readily understood that the studs l5 not only prevent wear upon the tire and the tread of the protecting casing, but also act as non-skid elements and prevent skidding of the tire and wheel. When the studs 15 are worn down to such an extent that skidding might occur, they may be removed and new ones readily put in their places.

The casing when assembled and in place on the tire is so made that at the bottom of eachiside o1" the tire, just above the rim of the wheel, there is a small part of the tire, as indicated at 16, not covered. This is constructed in this manner so that the cas# ing can work with the tire and there will be no chance of the casing kneading or buckling against the rim.

As shown in Fig. 3, the studs or calks are placed three in a row across the tread, the rows about two inches apart, with one calk in the center of the space between the rows.

From the foregoing it will be observed that the members 3 and i extend entirely around ofa single piece. They will be of thin flexible material so that when applied and'seV Cured, as shown, `the ,protecting casing Vformed thereby will readilyv give up and down with the spring of the tire,` while at the same time, it will protect the tire from punc turesand from the roughness of the lroadbed. The tread 11 will, ofcourse, take the major portion of the wear of the tire by direct engagement with the road-bedand will be of a suilicient thickness to spring withor follow the movement of the tire due toV the weight of the vehicle. lt is of v sufficient thickness to withstand the blows from rocks, stones, etc, l Y- By making the member 3 cover about twothirds of the tire 2, the member 3 can first beapplied to the tire when in its deflated condition and' while in this deflated condition the bolts 5 can be passed through registering openings 8 andV 9 of the overlapping portions of the members `3 and e', and the screws l0 applied thereto. At the `same time the members 3 and ,4 can be removed from the tire should it become necessary to do so.

Having lthus described my invention, what Y I claim and desire to secure by Letters Patent is ra Y Vl. The combination with a pneumatic tire casing, of a detachable sheet metal Ytire protecting casing embracing and tightly fitting the entirev outer surface of the casing from points adjacent to or slightly` removed from 'the inner periphery of the casing, the sheet metal casing comprising a wide sect-ion and a narrow section, each a complete circle and curved in cross-section corresponding to and tightly fitting the outer surface of the tire casing, the wide'sectio'n covering approxi ing the remaining third of the tire' casing, the adjacent edges of the sections overlapping and lirmly' kdetachably connected, whereby'the'sheet'metal casing is held to the tire casing solely by the inflation thereof and attachable thereto and detachable ytherefrom.y Y Y 2.1The Acombination with a pneumatic tire casing, of a thin sheet metal protecting casing embracing the outer surface of the tire casing from'points adjacent the inner periphery of the tire casing, the sheetmetal casing comprising a wide and a narrow part, each a complete circle and curved to correspond to and tightly it the outer surface of the k tire casing, the wide section extendingl 1 across the tread of the tire and the narrow casing irmlyand detachably connected to that edge ofthe tire section nearest the tread of the tire, 'whereby the sheet metal is held to the tire. casing solely Vby the infiation of the latter and is attachable thereto and detachable therefrom.

3. The combination with a pneumatic tire casing, of a thin sheet metal protecting casing embracing the entirefouter surface ofA the tire casing from points adjacent the 1nner periphery of the tire casing, the sheet metal casing consisting Vof two sections, each a complete circle and curved in cross-section to correspond to and ltightly fit the cuter surface of the tire casing, the wide section extending across the tire tread, and the narrow section lapping the edge of the wide section nearest. the tread of the tire and detachably and firmly connected thereto, a proliecting annular tread the outer' surface of the wide section opposite the tire tread, whereby the sheet metal casing is held to the tire casing solely by the iniiation thereofand is attachable thereto and detachable there from.
